Answer: 24
Label the time slots as A,B,C,D
For time slot A, he has 4 candidates to pick from. Then for time slot B he has 3 choices left (he doesn't want to interview the same person again), and C has 2 choices, with D having just one choice. Effectively we start at 4 and count our way down to 1. We will multiply these values out.
Overall, Bob has 4*3*2*1 = 24 different ways to arrange the candidate interviews. This is known as a permutation because order matters.
4 cups....
First, change the proper fractions to improper fractions.
2 1/4 = 9/4
1 3/4 = 7/4
Then, add the improper fractions.
9 7 16
--- + ---- = --------- = 4
4 4 4
4 cups of peaches and pears
(3,y),
4x-2y=24
4(3)-2y=24(substitute x with 3)
12-2y=24
-2y=24-12(subtract both sides by 12)
-2y=12
y=-12/2 (divide both sides by -2)
y=-6
Answer
(3,-6)
Answer:
(0, -2) and (2, 0)
Step-by-step explanation:
The solution to a systems of equations is when the x and y values are equal for two equations. This can also been seen as when the two equations intersect. So by looking at the graph you see the line and the circle intersect at the point (2, 0) and (0, -2) which are going to be the two solutions to the systems of equations.
